ROUBLESHOOTING
Before contacting Humminbird Customer Service, please read the following section. Taking the time to review these troubleshooting
guidelines may allow you to solve a performance problem yourself, and therefore avoid sending your unit back for repair.
Control Head Doesn’t Power Up
If your control head doesn’t power up, use the Installation section of this manual for specific confirmation details, making sure that:
• the power cable is properly connected to the control head
• the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground
• the fuse is operational
• the battery voltage of the power connector is at least 10 Volts
Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if
necessary.
Control Head Doesn’t Detect the Connected Transducer
A connected and functioning transducer will automatically be detected by the control head. The control head will default to the
transducer that was included with your unit and automatically select sonar settings based on the transducer’s capabilities. If, when you
power up the control head, it does not automatically select sonar settings or display sonar data, even though a transducer is already
connected, this means that the control head is not detecting the transducer. Perform the following troubleshooting tasks:
• Using the Installation section of this manual, check to make sure that the transducer cable is securely connected to the control
head. Reconnect if necessary, and power up the unit again to see if this fixes the problem.
• Replace the non-functioning transducer with a known good transducer if available and power up the control head again.
• Check the transducer cable. Replace the transducer if the cable is damaged or corroded.
